To read the full article Peer-reviewed Article PDF image


Information and computer security are supported by the passwords, as passwords play a vital role in authentication process. The traditional authentication method uses text- based passwords, which is also called as alphanumeric passwords, is not reliable in data security, and to overcome these drawbacks, graphical password scheme is introduced as an alternative to text-based passwords. But graphical password scheme is vulnerable to shoulder surfing attacks, spyware attacks. To overcome this vulnerability of graphical passwords, an emerging technique CAPTCHA, as a challenge response test is generated to distinguish humans from bots in authentication. To ensure security on hard AI problems, CAPTCHA as graphical Password (CaRP) scheme is introduced as an alternative method to textual CAPTCHA’s. As CaRP scheme has scope of refinements in cyber security a two-way authentication method is proposed in one of the CaRP techniques of Recognition-based scheme.
